Some of the best alehouses are no longer new and interesting (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
stale
'no longer new and interesting' is the definition.
I can't tell whether this defines the answer.
'some of the best alehouses are' is the wordplay.
'some of' indicates a hidden word.
'STALE' is hidden within 'best alehouses are'.
Can you help me to learn more?
(Other definitions for stale that I've seen before include "Mouldy or hackneyed" , "No longer take" , "past the sell-by date" , "Lacking freshness" , "no longer bearing interest?" .)
